   An update that fixes one vulnerability is now available.

Description:

   This update for openssl-1_1 fixes the following security issue:

   * CVE-2021-3449: An OpenSSL TLS server may crash if sent a maliciously
     crafted renegotiation ClientHello message from a client. If a TLSv1.2
     renegotiation ClientHello omits the signature_algorithms extension but
     includes a signature_algorithms_cert extension, then a NULL pointer
     dereference will result, leading to a crash and a denial of service
     attack. OpenSSL TLS clients are not impacted by this issue. [bsc#1183852]
